unit 4 review

The Scientific Revolution and Enlightenment reshaped European thought. Rationalism, empiricism, and the scientific method challenged traditional beliefs, while new political theories like social contract and natural rights emerged. These intellectual shifts had far-reaching impacts. The American and French Revolutions applied Enlightenment ideals, while the Industrial Revolution transformed society. Scientific breakthroughs and philosophical movements continued to shape the modern world.

Key Concepts and Theories

  • Rationalism emphasizes the use of reason and logic to understand the world and acquire knowledge
    • Descartes, a prominent rationalist, developed the concept of methodological skepticism to question existing beliefs and arrive at certain truths
  • Empiricism stresses the importance of sensory experience and observation in gaining knowledge
    • Locke, an empiricist, believed that the human mind is a "blank slate" (tabula rasa) at birth and knowledge is acquired through experience
  • The scientific method involves systematic observation, measurement, experimentation, and modification of hypotheses to understand natural phenomena
  • Deism holds that God created the universe but does not intervene in its operation, which can be understood through reason
  • The social contract theory proposes that individuals willingly surrender some freedoms to a government in exchange for protection of their remaining rights
    • Hobbes, Locke, and Rousseau each presented different versions of the social contract theory
  • The concept of natural rights suggests that all individuals have inherent rights, such as life, liberty, and property
  • The separation of powers divides government into distinct branches (executive, legislative, and judicial) to prevent any single branch from becoming too powerful

Chronology (c.1648–1815) and interpreting how intellectual changes affected political and cultural developments also trip people up.
